I sent these guys a roll of Superia 400 - it came back within a couple of days and the scans are fine for proofing / web stuff - probably even small prints. Excellent value for money at 4.
It took a while to get around to using them, but I just got 10 rolls of XP2 and Ektar back on Wednesday after posting Monday. Processed and scanned @ 4 a roll 3024 2005 (6.1 MP). I'll rescan the best shots, but on the whole this was a good job and very good at the price.
I've also had good results with labs using Noritsu (for example) I've just moved back to Australia and used a local service (Photocontinental) and they use the Noritsu as well.
Scans are what I have come to expect from the Noritsu, but their pricing was .... far less attractive AU$20
