I'm mildly dyslexic, that's why I re-read what I've written and amend it if I spot a mistake; not really an excuse, more a reason really. Anyway, back to your post. Yes, some enthusiastic pro photographers will often have a play with some new bit of kit, or perhaps experiment with a bit of vintage kit. However, the way I read it, the OP's question was do pro photographers use entry level kit in their daily jobs, not purely to evaluate something or have a bit of a play.
To answer your question, I've met/known a few pro photographers over the years, and from what I've seen they've all used pro-quality cameras and lenses for their main kit when doing their 'day job'. I've also met a few part time/semi-pro photographers, and a number of them have used a mixture of semi-pro/enthusiast grade kit, occasionally with some pro grade kit as well (depending on their budget and needs I suppose).

Anyway the point you made earlier was that professional photographers only buy equipment based on business needs, all I was saying was that I know that is not the case for a huge amount of pro photographers, myself included. In my experience and I know many professional full time photographers they are as gear hungry as anyone else sometimes more so.
You clearly don't like someone having a different opinion than you though, hence the childish remarks about spelling. To be fair, pettiness does seem to go along with your online persona, as I have seen you make other similar comments on here before when someone disagrees with your opinion.
