Bill and all,

Although the grocery store oven liner will work, I prefer not to work on 
a fully conductive surface because I don't like the idea of accidentally 
shorting two things together when I lay them down, but YMMV.

Good anti-static mats can be inexpensive.  Check out the ones at 
TigerDirect (www.tigerdirect.com).  Their ULT33122 is a 23.5 inch square 
mat for $19.99, or if you want something larger, the ULT33121 is 23.5 x 
47.25 inches for $24.95.  Their wrist strap is ULT31418 priced at 
$6.99.  Other computer related outlets should have comparable prices.

An ESD safe work area costing around $30 should be palatable for most 
builders - that is roughly in the range for the cost for one replacement 
firmware chip from Elecraft, better to be safe than sorry.

73,
Don W3FPR
