Keyboards to try on a budget

For those of you who are keyboard crazy like myself, you know that this hobby gets pretty damn expensive pretty damn fast.

So here's a list of inexpensive keyboards you can try, if you want to try some interesting keyboards on a budget.

• Microsoft Natural Elite: This is the basic ergo keyboard from Microsoft. It's their classic design with some annoyances like the diamond arrow keys and the non-standard pg up/down block layout. You can also try the Ergo 4000, though I would recommend against it.
• Keytronic keyboards: These guys are basic rubber dome boards, only slightly more expensive than your standard rubber dome board, but have a very distinct and good feel for a rubber dome board. Make sure you check out the specs and look for a keystroke life of 10 million strokes+, otherwise you're getting one of their cheap ones, which are the same as everyone else
• Thinkpad keyboard: This is the keyboard from lenovo for folks who like the thinkpad keyboards and want one for their desk. There are two models, the big one with touchpad and numpad, and the new one without (and modified esc and delete keys). They have the classic Thinkpad look and feel.
• Buy it on ebay or a shop that sells old parts. A lot of the older keyboards still use switches from ALPS and Cherry, and you can often find them extremely cheaply if you know where to look. You can try things out this way before you invest in that Filco, Topre, or unicomp
