You asked for an example of unprofessional answer - here it is:
In my original thread Erik just advised me to try needhams - I tried, here are the results: the proposed programmer is more than two times more expensive that the whole quantity of chips it is supposed to be used for (Erik disposes of this data), plus on-line purchase is not available. You think it professional?

I advised you to try needhams. You asked whwre to buy a cheap programmer, I know that Needhams is about the cheapest available.

Evidently you want me to look up the price of your chips and the price of the programmer before answering i.e. spend my time doing your work.
In other words, answering your question as stated I told you where you could look for a cheap programmer and that is it. Stating that needhams have cheap programmers is correct, what is unprofessional about stating a fact?
