Rick,
I do something similar for the young kids.... it's usually is something like;
"Yep, if you don't buy this one... I'll certainly do you right on the next one you want me to look at"
Planting that seed is something that I can always feel good about telling kids who don't have two nickels to rub together.
Of those re-inspects, quite often, I'll give too much away (monetarily) to help out the kids just starting out. Hell, many times I just flat told'em to just send me their family/ friends and relatives business... Everytime, I get paid back 2 fold.
