Unfortunately I believe Suma are most prominent in the Eastern market and they certainly don't respond to emails. I would expect these '4300' cards to cost as much as a 4400 anyway, so you'd prob be just as well getting one of them, or better still get a 4200-128MB, even with 4.0ns TSOP RAM 300/550 is not to be sniffed at considering the prices.
It is VERY difficult to find the ns rating of the RAM, in many cases the manu's and sellers don't even know it themselves!
UK:
www.dabs.com sell 4 4200-128MB cards (Inno3D/DabsValue, Abit, Albatron and Aopen) and none state the ns of the RAM they use, even when checking on the manu's website.
www.komplett.co.uk sell 2 4200-128MB cards (Asus and Gainward) and again no luck.
www.insight.com/uk don't appear to sell any 4200 cards LOL!
www.simply.co.uk sell 4 4200-128MB cards (Gainward?, Albatron, Sparkle and Creative?), Creative's website only has 1 link for a 4200 but I believe they do 128MB and 64MB versions, in any case the high res picture they provide clearly uses 3.6ns RAM (but is probably the 64MB version).
www.watford.co.uk - site is down 26/07/2002 03:15am
www1.novatech.co.uk only sell 1 4200-128MB card (NovaTech), once again no info on the ns rating of the RAM.
Australia:
www.auspcmarket.com.au sell 3 (Triplex, X-Micro), nowt.
www.techbuy.com.au sell 3 (Triplex, Sparkle and Leadtek),
I checked all manu's websites except Triplex who seemed ellusive, how about you trying some ground work now? You can try reviews of 4200 cards, maybe they can help as I know I've read reviews of 4200-128MB TSOP 3.6ns cards.
