You are bound to want to program other chips soon. Farnell (Leeds) sell Picstart+ for 109 Pounds Sterling inc VAT. (Probably $109 by the normal exchange rate). It will save you having to buy a ZX80 programmer. I have been poor once - go for it - you will make it pay if you are serious. Dont expect miracles from a cheap beginners item, however good and cheap. Think positive. Learning is a great asset.
