Thanks to everyone who responded, on and off the list. I thought I'd post a quick summary.
To clarify my question slightly (if belatedly) I'm specifically looking for a passive 3D solution to plug into my MacBook Pro whilst on sabbatical in the USA. I'll be using it for a mixture of 2D and 3D viewing, not for many hours of dedicated hand building of my 3.5A maps. Well, I hope not! ;) The LG D2343PB-BN gets honourably mentioned, and is available in several places: http://www.adorama.com/LOCD2343PBBN.html $273.50 including shipping http://www.bhphotovideo.com/c/product/1002116-REG/lg_electronics_d2343pb_bn_23_mon_led_lcd.html $273.50 + shipping Another candidate is this from AOC: http://www.amazon.com/AOC-E2352PHZ-23-Widescreen-Flicker/dp/B005LORQGG $250 including shipping The Asus VG27AH also got good reports, but is listed as either 'out of stock' or 'unavailable'. However, its kid brother, the VG23AH is available: http://www.pinnaclemicro.com/computer/dsku.php?g=VG23AH&m=ASUS $251 including shipping (you need to enter the promo code SAS10 to get $10 off!) This monitor got a poor review on cnet (http://reviews.cnet.com/lcd-monitors/asus-vg23ah/4505-3174_7-35306085.html) but much better and more thoughtful reviews elsewhere (http://3dvision-blog.com/7861-review-of-the-23-inch-asus-vg23ah-passive-3d-ips-display) so I'm going to go with the Asus for the following very scientific reasons: 1) It's $20 cheaper than the LG 2) The colours felt a bit washed out on the only AOC monitor I've used previously 3) It has built in speakers and I don't have any on my desk My feeling is that these will all perform in a very similar fashion - I'll report back once I've plugged it in! cheers Shaun
