just looked at overclockers.com....
they have a link to
ExcaliberPC.com that has guaranteed xp1700 tbredB JIUHB 0302 for $56 USD with $4 flat rate shipping(located in Fremont,CA)
and as already mentioned,
Vibe Computers has xp1700 tbredB's JIUHB (previously JIUCB's) with unknown chip dates for $98 CAD / ~$64.50 USD with close to $10 CAD to ship to me, your mileage will vary (located somewhere in Canada)
both places are offering xp2100 tbredB's for about double the xp1700 prices
happy overclocking!
