I've purchased several items from wheeljackslab in the past (three or four in the past month) and have always received a great item at a great price, very well packed, and shipped pretty quickly. I think you need to look at his ratio of positives to negatives to get a feel for how likely you are to have a bad experience with him. He moves a lot of merchandise and gets a lot of feedback, most of which are positive (99.5%). Pretty good track record, IMO.
I've also bought items from Wheeljackslab. In the last month i've bought 5 seeker jets and wheeljack from him. All were G1 non reissues with C9 or better condition and all parts. He really has some great items for sale but the great part is his pricing. I remember a few years back trying to buy his stuff and it was overpriced to death. It seems these days he's really come around. I would reccomend him to anyone looking for a good deal. He even has want ads where you can request items for him to sell you when he gets it.
Good ebay seller: wscato, who I think is also a member of these boards. I bought a Powerlinx Optimus/Megatron TRU combo from him, and it had arrived within a few days, in excellent condition. I've bought stuff from him in the past as well. I'd recommend him.
Tfsource threw in a WST Prime as a "Christmas present" for ordering a Masterpiece OP trailer from them. Awesome guys!
Peter-Albin Can't speak highly enough of him. The guy has great communication, and gives brilliant customer service. Shipping costs were an issue so he stripped the outer bubble, backing card and catalogues out of the Stormjet (6019843393) and Barricade (6015806514) which I bought from him. He's definately a seller whom I'd happily recommend to anyone.
Omega One Prime on eBay: http://feedback.ebay.co.uk/ws/eBayISAPI.dll?ViewFeedback&userid=omega-one-prime&iid=220004829567 Superb. Delivered in one day. I'll definitely be dealing with him again. I wish dit138 would answer his ebay questions; I wanted to buy a G1 Fortress Maximus shell from him, and asked about shipping, and he never got back to me.
etoyer Shipped everything out quickly, arrived within 2 days, plus it was in C10 casefresh condition.
I have few... a-place-in-space Comics eBay seller, quick shipping and comics well protected. niccijush A bit pricey, but my G1 reissue traversed the atlantic in under a week and it was well protected. Communication was good also. Toyspark Usually pretty good, the toys are usually shipped in polystyrene. Communication can occasionally be hard work. toysbuddy Another good Hong Kong seller. gerrutcamaro Dutch seller. Good communication, and quick shipping across the English Channel. ksgj03 An excellent seller in Singapore. My MISB transformer arrived relatively quickly, and it was well protected.
I've recently completed good deals / smooth transactions with: * harryknuth * greattoys-greattoys * dit138
liqdeal and ksgj03 liqdeal (ToyArena) is a great seller. I think I've bought 6 or 7 things from him i just the past 2 months, plus a couple before that, and never had one problem. Good prices, has charged me actual shipping charges with nothing trumped up, and ships really quickly. For example, I just bought a set of Korean NEO vs. packs on Saturday... they arrived, extremely well packed, on Wednesday. Pretty good timing, but that was actually one fo the slowest times from him. ksgj03 is another good seller. I've only bought one thing from him, my MISB Big Covnoy vs. Magmatron set (my Holy Grail!) and it arrived pretty quickly from Singepore and was packed extremely well!
jj868 just orderered a few toys that were in great shape, very well packed and pretty fast shipping and pretty good pricing, great communication
vince.carter15 Just ordered The Fallen from him and it arrived in the UK from Hong Kong in a week, definitely recommended!
TIMBAN in UK is awsome. he is a personal friend of mine now after dealing with him for around 5 years. can get almost anything you ask for and at a good price. always combines shipping too. personal deals always smooth too. credit to UK collectors. plus DIT138 is awsome for parts to G1 TFS
