I’m with ameritrade and when I sell stocks, they make you wait three days until the cash settles, then you can use the profit to buy stocks again. Is there any stock trading company (etrade, scotttrade, charles schwab, fxcm) that doesn’t do that?

Can anyone recommend me an online trading company such as ScottTrade, eTrade, AmeriTrade, etc. Which one offers low fees and can u tell me about your experiences? I want to purchase a thousand or two of a low priced stock, what are the boundaries if I wanted to take the money back out after a year of positive growth? Please help, economy *****.
