In general, is it OK to recommend an aviation product (that I have found
very helpful) in a newsgroup?

There is a rec.aviation.products newsgroup specifically for that purpose.

True, but it depends on the product. The .product group doesn't get a lot
of traffic, and -- if it's something we all could use -- why not bring it up
here?

Generally the best way to go about this in the .piloting group is to pose it
as a question, like "What do you guys think of 'x' product?"

If it sucks, you'll soon know it. And at some point you'll have a chance
to toss your two cents in...
