Lithium Polymer battery suppliers

Can anyone recommend some reliable Lithium Polymer battery suppliers? Unfortunately Google supplies a vast number of pages. I'm looking for sites that cell single cells (naked) at decent prices with a wide variety of sizes to chose from. I'm looking at two extremes right now, extremely small cells for micro RC projects and larger cells for power backup/extension So basically 500mha and lower and 5000mah and higher. Any suggestions for a good supplier would be appreciated, especially one with a wide variety of form factors.

I have found this site which fits the micro RC nitch quiet well
Thin (1 mm) to Ultrathin (0.5 mm) Rechargeable Lithium Polymer Cells from PowerStream, but am looking for a wider assortment from a single supplier.

I've been using all-battery.com , but I can't say I've done an exhaustive search for the best prices.
