"Zcomax seems more of a mfr than a reseller, but they still sell their products direct to the end-user. Since their cards are so hard to find I just ordered from them. The XI-300 is a very well-engineered Prism2 wireless card with a detachable antenna so you can use the RP-MMCX connector. They also sell a small dipole antenna you can velcro to the top of your notebook lid. The XI-325HP is a 200mW(!) Prism2.5 card. Other wireless products are available as well. Prices are good considering how hard it is to find Zcomax products. You have to email or call to get prices and place order. Customer service was very good. Salesperson talked knowledgeably about their products and was helpful."
