do you want to sell it
even now it is a very good programmer, keep it.
I have a dataman 48 ... who is a renamed beeprog+ i love it, with the isp connector, very practical, but i hate the software interface a bit.
The problem is with the adapters, Elnec charge $$$ for whant you can find cheaper on Ebay.
You can ask for at least 200$ for it, i have paid mine 550$ (used).
tl866 is a lot cheaper than your programmer, wont support as many ic's than you Elnec "bk 866"
