I forgot about this post...
Here is my humble contribution.
The first 10 are ones that I have a good amount of gametime on. ALL of these maps will be in rotation here ( 8.6.3.240:27015 ) for the next 7 days or so.
#1-pg_icepick, dm_icepick no question, damn near perfect and almost alive,

2-dm_drift_revised, great sense of place, gameplay excellent, performance good. Originally released in 04 though

3-dm_compressed_r1, not the prettiest but strikes the balance between performance and gameplay perfectly, great layout
http://www.fpsbanana.com/mirrors/startdl/1?path=http://files.fpsbanana.com/maps/dm_compressed_r1§ionid=620714&ext=7z
4-dm_gaunt_greenlet, very fun map with a strange vibe, though I am unsure if it's a remake
5-dm_montana, nothing terribly new but very professionally finished
http://www.leveldesign.eu/artikel/?id=4
6-dm_feudal, fast as hell and fun even though I hate bounce pads, remake
http://files.filefront.com/dm+feudalbspbz2/;7858219;/fileinfo.html
7-dm_urban_day_07, proven itself fun to play and full of subtle details though bad on the fps
8-dm_armageddon, another promod rerelease, fast fun
9-dm_tobor, strange and beautiful and also cramped
10-dm_corrugated, nicely executed but marred by poor weapon placement
http://www.fpsbanana.com/mirrors/startdl/1582?path=http://www.rustednut.net/fpsb/maps/68/dm_corrugated§ionid=613948&ext=zip
hm's, mostly because of no playtesting or performance issues
-dm_3006_beta, great vibe, have not seen it online
-dm_octagon, released 12-22-06 but very worthy of mention despite being a remake
-dm_biological, sadly broken release
-dm_hiatus, concept comes together with personality, looks great
-both versions of dm_crossfire, one keeps the engine under control, the other does not, though I dislike the gameplay
-dm_uncivil, good imagination and runs nice too
-dm_campgrounds_pro, nicely performing remake, bad on the rpg
-dm_cannon, broken on linux?, beautiful work
-dm_moroes, beautiful yet very frustrating to play
-dm_weaver, perfect execution, limited gameplay ( please expand this map! )
-dm_moil, nice finish, performance hit
-dm_outyling_beta, what outside maps should look like, performance issues
-dm_meatgrinder, redlining the engine without overheating it
-dm_walkway, no playtime here, can't get bzip to crunch it for some reason
-dm_thefactory, decent layout, good performance for what it is.
Good work everybody; HL2DM ftw
