Projectors are inherently unreliable---compared to other monitor devices (Flatscreens, CRT's, etc.).
That said, I don't think the 'weight' of the PJ is a good indication of it's potential reliability. I've been on these forums for a while and have read many PJ threads and it seems no model, cheap/lightweight or expensive/heavy is immune from issues. But more to the point, I haven't seen any reliability trends favoring heavier more expensive PJ's.
I owned a cheap, lightweight and very hot to the touch Optoma H31 DLP for a good 6 years, no problems. But, I did have early issues with buzzing power supplies on the H30 model (not H31) and teething issues with the first run of HC3800's, but after that, no problems (knocks on wood
But, I wouldn't buy a PJ if you expect it to work for 6 years of heavy use (minus lamp replacements). I think 6 years of heavy use with no problems would be the exception with PJ's, not the rule. This is why it's important to get a brand that offers not only excellent warranty service, but at least 2 years warranty (like Mitsubishi does). It's also one of the few (if only) products that I think purchasing an extended warranty is worth it, though I haven't done it myself (living life on the edge
