I do indeed have preferences, but since this is an open forum it's nice to see what all the options are rather than impose my own. That way everyone can win.
I've tried both but unfortunately I get 2-3 sp's with 10-20 ads each. If Leo's had a wildcard type search it would be all good, but instead you have to try all sorts of crazy characters between the letters to find ads.
Easier if we collect the info in one place methinks.
