Don't sweat the small stuff. A good investment is a stock that has strong prospects to double or triple over the next several years. A few percent difference in what you buy it at is not going to be a big deal.
I bought a bunch today, some slightly above 23 and some slightly below.
The proof of the pudding will be whether this thing a few years from now is in the 70-80 range or in the 10-15 range. Whether I bought at 22 or 23 won't make that much difference.
