I've owned several KLRs. I certainly wouldn't call them reliable, though they were cheap and relatively easy to repair (assuming that you have access to a new one of whatever broke or fell off). They definately dont last forever either, but they're not really supposed to. 40,000 miles and then throw it away and buy a new one. You can essentially buy 3.5 KLRs for the cost of a GS (US market), so there is a strong arguement to be made for the more disposable KLR. Having said that, I simply got tired of the crap suspension, terrible brakes, and lack of power in my everyday bike. If I was planning on riding through third world countries or very remote locations and all that really mattered was making it through with the least hassle, I'd probably get an XR650L or DR650.
