I found the following from Ebay 100 20 MHz crystals for $9.99 with free shipping: <http://www.ebay.com/itm/280889781739> 16 X 2 displays for $2.22 each free shipping: <http://www.ebay.com/itm/LCD-Display-Character-Module-LCM-16x2-HD4478-Controller-Blue-Blacklight-1602-HK-/141167832556?pt=LH_DefaultDomain_0&hash=item20de422dec>Now is I can find some TO-39 (same size as TO-5) heat sinks at a reasonable price. The ones I have found so far cost more than the 2N2218 transistors!
