I know we have discussed the merits of making one's own staff vs. buying one, but... I found this the other day on Ebay
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=1980753770 . The seller has a number of them for sale, to see additional listings, just hit the seller's other auctions button. Looks like it could use some upgraded items and items that are not included. The seller has listed several so there is not much of a bidding war. If interested you should be able to pick one up for around the starting price of $20.00 plus $8.00 shipping. I did buy a couple to examine and give as gifts. The seller said he would not be selling on Ebay after Christmas, but will seller directly. For what it is worth. Pete
