Welcome back to the hobby, and welcome to the forum! If you have anything else you'd like to tell us about your interest in this hobby, add a post to this thread
You can end up spending a lot of money, especially if you're too impatient to wait for the good deals, or don't have enough time to search eBay incessantly. I sure blew a lot of cash when I first dove back into this hobby. I'd like to think I'm wiser now, but the truth is, I don't even have enough time to find ways to waste my money!
