Check out other keyboards too; not just mini. If prices are too high, at least it will give you an idea of many that are available. Then you have a good base for searching on auction sites. BTW.... I have the HappyHacker Lite. Size is great but the keys seem "loose"; not a tight keyboard. I, also, have a CQ that is just a little larger than the HH (top to bottom). I like it a bunch more. I haven't been able to locate that particular brand but saw some that resembled it at above sight. It has more of a feel of a top notch, very high quality, notebook keyboard. I purchased it at Fry's for around $30-$40US but they haven't had any more several times I check in past couple months.
I, also, have a TI industrial, micro keyboard. It is a super backlighted little dude BUT keys and spacing are too small for regular "typing" use. It is very expensive retail but can be found occasionally on eBay. I would not recommend this for everyday use.
