They're very solid, not the best ones around in terms of performance (wirespeed) but they are very reliable. Good up to ~300mbit total WAN-traffic or so at least running OpenWRT. I've been playing around with a D-Link DIR-860L B1 right now and as far as overall performance goes it's very impressive (about 50% faster) although I have no idea how well wireless works (yet).
