I have a few builds that I'm not satisfied with. I put them back in the box with all of the loose parts and mark it unfinished. It goes back on the shelf. After a while I'll be looking for something to build and go back to it. A second approach usually has good results. If I look at a few months or a year later and still don't care for it I use it for spare parts. I feel that if you walk away from it for some time you can get back into the groove and revive it.
I laugh everytime someone says ebay is a rip off, or I don't use ebay. You know, it's like listening to the radio. If you don't like the music do you unplug the radio and never use it again? No, you change the station. If you don't like anebay seller , just change to another. If you think they're a rip off, don't do business with em. I absolutely got my best deals ever on ebay. I'm not cheap, I'm not rich, I look for the best deal.
