I spent $92 dollars on seasons 1 and 2 of Transformers Animated just this past summer. Obviously it was extremely expensive, but I think it was worth it or perhaps I'm just crazy
By far it would be what I've spent on my PS3, games, and peripherals. I wish it was my Transformers collection, but that will change after college.
I had a good $10,000 into my custom pickup truck before I sold it. That was over the course of 5 or 6 years. Probably about half that into my 'entertainment' hobby... 3D TV, surround sound, PS3, etc. I lost count of my TF expenses. It has been on-going since I was a kid but I never put out more than $50 for a figure and typically stick to the cheaper/discounted ones these days. Edit: Ok, I was wrong. I did spend $75 on Ultimate Prime recently.
The most would have to be MP-01 Optimus Prime. I paid roughly $150 dollars after shipping. This was back in 2003/2004. Needless to say never again. I've since learned my lesson. I have not purchased a Transformer since july. I have been focusing on other lines (most notable being DC).
I've always been into cars and modding them. Over a course of about 8 years I easily spent 75K plus purchasing cars, fixing them up and then getting another and doing it all over again. I always had these nice cars that I rarely drove because I was afraid they would be stolen so I always drove beaters around and left the nice ones at home. Only drove them on weekends. Vicious cycle that I got out of when I had my kids and have thankfully stayed away from. Unfortunately that addiction was substituted with Transformers as I've spent over 10k on TF's since the 2007 movie infected me. Mark
I spent a little over a thousand dollars on a new computer and a couple of games for it this past month. I'm gonna be in poor status for a while, but thankfully, it was worth it.
As a whole? Probably my Transformers or Bionicle collection. Y'know, probably the latter. But recently? Star Wars made a come back last year... I've speny a dickload on DOTM, and more than I'd like to admit on My Little Pony ($75). I think for 2011, Dark of the Moon has been the most expensive hobby. But the most I've personally spent on an item was $90 for the Lego Bionicle Skopio vehicle. Let's count that.
in one shot? almost 2000$ on camera equipment. Before tfs you wouldn't ever see me without a camera. Sadly, I sold ALL of it. I forgot how much everything cost me. All I remember was being depressed about it.
My Macross 1/48 VF-1S plus super packs, it cost me a total of around $210 or so after all was said and done, I don't regret any bit of it.
A lot. Transformers, paint ball, DJing equipment, video games... Yeah, more than I want to think about.
About $10,000 or more on reptiles and breeding racks for them. (i had a small breeding buisness) some of my reptiles where worth thousands.
