In the past I've used several different 8051 style parts. To date my only Flash uC experience is with pic's. I would like to get back to the 51 core. There are a lot of 51 flash parts available these days. Are any of these parts easier to program then others? Who is a good source to purchace them from? Besides DigiKey and Allied. I don't want to invest in any more expensive programmers or development boards.

Thanks
Brian
