I'd say go for it myself.

Regardless of what others think, I'm all for someone getting adventurous with their hobby; it's not always about the investment/return. Sure it could be a money pit but if you're having fun and trying something new who cares?

Sometimes it does make sense to spend more and create as affordability allows rather than try and save the funds in the hopes that someday you have accumulated enough to purchase a used machine with what someone else thinks is an awesome improvement at whatever the inflated price of the machine is at that time. I'd never have owned a Harley if I had to save for one, but the one I built piece by piece was an enjoyable experience and truly mine by the time it was done. When I eventually sold it I got nowhere near what I put into it, but I couldn't begin to put a dollar value to the fun that experience brought me.

Hobbies are about exploring and enjoying, and if you think you can achieve the end result and be happy with the journey then why not? My only suggestion (and it is just that, a suggestion) would be to exercise the obvious and research the heck out of it to avoid potentially getting frustrated with it and stopping at some point. Hopefully it won't happen but if it should, there is a vast number of those on here that you can draw upon for support and assistance.

I often wonder at times about the direction this site seems to be going, and refrain from posting often because of that.....it is still a hobby, not a mutual fund for subsidizing/funding your eventual retirement. Have fun with it....

Just my .02 for what it's worth...
