Hi DaveL,
For 8$ for a 4/5'', I consider myself that they are worth it.
Collecting local trees cuttings can be troublesome (human relations can be) but the most "worth of it" path.
Because you could get some for free; you could see (ok, let say spy) with your own eyes how adapted the tree is to your locales and the gardener could remember what the "fig of a damn strain" he bought.
Well in real life, most don't remember ... You know the "it is a dark fig" or "it is a white fig " or ... "I still don't know, but supposedly... "
So buying cuttings, the worst you could end with, is an unproductive fig tree, or a mislabeled generic one .
Now, comes the most important point to me : How many bucks ? And you're the judge for knowing if the amount is worth your buyer's risk .
I would say, try some, but remember that it is a lottery except that there is no quick big $$$ lot to win :) .
On the other side, you could find a good unknown strain ... So really up to you.
Perhaps, buying here on the forum - since you can, where I can not :( - is your best bet .
You could try local sales in the streets or local farmers market and see what you could find .
I did find a small tree for 8€, and to my big surprise she is my "unknown green longue d'aout" - a really good one.

Only serious advise: Don't overrun your capacity for fig trees... But, I myself already did :), but try to be stronger than me, I'm sure you can (try)... :P
Only thing for sure: You'll be taught patience ... I was and you will be.
