Should I buy a MakerBot?

I've been watching the at-home 3D printing machines for a while now, and each year they end up being better and better. I feel that at some point I will own one of these wonderful devices, the question is when.

My main worry is that my complete lack of skill with 3D modeling programs (specifically Blender) will become an issue. However, after reading about OpenSCAD and all the ways that it can import and manipulate in code I feel a lot more confident. Is this really an issue, or are there enough awesome things on Thingiverse to tide me over?

I've also heard that using one of these is as much a lifestyle as it is a tool, but perhaps they were speaking more about the Rep-Rap. What sorts of maintenance and upkeep will I be looking at? Oiling and a little adjustment here and there, or will I be jumping feet first diagnosing problems I have no clue where to start with?

I put together an EggBot recently, so I don't think I'll have to worry too much about assembly. I'm mostly looking for guidance on how to answer these questions for myself, so any suggested resources would be very welcomed.
