Cisco Catalyst 4000, may be a bit overkill if you only want 36 ports and not looking to expand though.
Or you could look into 3Com stuff, such as their 3900, though I've heard some of 3Com's switched have stability problems, so if it will be in a critical envoirment, you might wanna make sure you dont pick a model that has those issues(I know the SS3300 switched has problems like that).
DLink has probabaly also got something like that.
