You can start with as little as $50 but you have to pay using ggole checkout or bank transfer.
Mindgenies, is that your registrar?
If so,
The $.03 tasting fee is nice, but is it really charged even if you keep the name? At $9.99 per .com, it seems a little much to charge the tasting fee, even if it's only a few cents.
With Moniker, if I taste 100 names and keep 50, I am charged 347.50
for the 50 purchased names and 12.50 for tasting the other 50.
With dotcomgenie, if I do the same thing, I am charged $499.50 and $3.00 for the tasting.
Now, I understand a 50% retention rate is pretty high, and I know there's a point where the lower tasting fee would trump the lower reg fee, but I would suggest at least considering this to let people test more names:
Set the amount being deleted from someone's balance for registering a name to your cost. If they keep the name, THEN charge them the $9.99.
