RepRap has the best hobbyist following. That is where I would look first. Other then that, get the most items in a kit for the price. If you can find a kit that has everything, go for it. I personally have a Makerbot Replicator 1 that I got off Ebay for dirt cheap ($1200). I love it. It’s lasted 5 years with regular maintenance, and only replacing the motherboard ($100) with a newer version from FlashForge that didn’t have power supply issues.
If I were you, I would look on Ebay or even craigslist. Unless you really want to build your own and already have electronics and software experience.
