I eventually get fed up with the various ReSharper builds I've been using for the past 7 months; the stability has been going steadily downhill since build 208 and performance is yet to improve. 217 originally seemed stable but turned out to be useless both for VS2003 and VS2005. I've been waiting in vain for a build as stable as 208 (which was practically beta-ready) but to no avail.

Eventually I broke down and installed the official 1.5.1 (build 164) for VS2003; unfortunately there are no official builds for VS2005 as of yet. I must say working with the official version is a pleasure - it's absolutely stable and, even more important, fast. So fast, in fact, that it feels just as responsive as the "regular" VS2003 IDE is, and the only drawback is a small increase in startup time.

I'm tenacious so I'll probably check the beta builds again when 218 is out, but in the meantime I can't help but feel pleasure in working with a mature product.
