Also, what questions do you have about what you need? I and others will be glad to try to help. As long as you have an ethernet connection on an external DSL modem (and not one of those damn USB modems) you likely can connect just about any router. There are a lot of different features in different brands, but with one exception (and early Belkin model that has since been discontinued) all have worked fine for me and worked well with Knoppix. If you can still find routers that are wired only they should be the cheapest, but 802.11b and even 802.11g routers (which usually also have 4 wired 10/100 ports) are becoming extremely cheap. I would think you might as well buy one with wireless capability, even if you are not going to use it at the momnet, unless there is a premium cost for it.

802.11g is faster than 802.11b (rated at 54mb/s vs 11 mb/s) but even an 802.11b router is bottle-necked by the DSL connection and not the wireless speed, so if the wireless computer is used primarily for Internet access then you'll see little or no difference. Obviously if you are transfering large files between systems on the LAN then the speed is an issue, but a wired connection will be significantly faster. If you want to mention a few of the brands and models that you have looked at we can try to give you some advice on what featutes one has that another lacks or how different manufacturers approach an issue.
