OK, maybe you could ask your BF and get his input on the share locking. I'm really curious his thoughts (or yours). I contacted Fidelity sometime back and they confirmed that when you setup a margin account, your shares can be "borrowed" (part of the agreement when you setup a margin account). For cash accounts, likely little-no impact (which is what I use).
At any rate, sure if you can grab 'em cheap do it! I have from .0021-.0056 (avg ~.00348). I'm not at all concerned about where we're headed here, it's definitely going up regardless. Sometimes a little experimentation can be fun, don't you think ;-)
