BTC was $10 in December, and I remember placing an order and then not being able to get to a bank branch in time, so I just thought "ah, screw it". Now it's about $14.20, heh. I'm hoping that it drops :/
Here is a nice price chart

It feels like if one bought BTC, it would be buying at the top.
I share you views somewhat, I loaded up late last year at $10 - although I stupidly bought through Spendbitcoins and paid a 10% commission so I could deposit cash at the bank and stay anonymous.
I really don't think the top is even close to being in though, bitcoins are divisible down to 0.00000001, so even if the rate some day becomes $100 USD = 1 BTC, it is still a perfectly usable currency down to small amounts.
Just look at total daily trading volumes to get an idea of where this could head as it becomes more and more accepted as a means of payment.
Silk Road alone could cause massive price increases as the growth there is phenominal, and after 2 years is proving it may possibly be unbeatable technology when it comes to law enforcement. It will only grow massively as more and more people realise how efficent it is, the global drug industry is over $300 billion a year and you will see more and more of that money flow through Bitcoins.
