If you have to ask the question, I think you've answered it. Only reason I've really considered one is because I occasionally would like to make something like a custom case or bracket but I've heard the dirt cheap ones (£80 ebay) aren't that good so I've decided to leave it.
Hmm..do I really need a 3d printer in my life? Can someone convince me please? :/
Oh I know - I got a V1!! However, at least those came with metal linear bearings! Never bothered with the stock bed either - went straight for silicon heat pad.
I wouldn't count on any being newest revision. You will probably find V2 version somewhere that's just how it should have shipped...
Like your thinking, much cheaper to print your kids bedrooms rather than moving house.
