May be other options for you, what do you want to use it for? If it is a defensive weapon, the word "cheap" shouldn't even enter the equation. You can go good value (if you have a P230 as your name implies, you already know what quality is). The 230 would suffice for a few months until you saved enough to get a used SIG (or other reputable manufaturer) 9mm in one of their frames. Just don't want to see you throw your money away on junk. If it is to keep somewhere that it may be stolen (eg a permanent car gun) so you don't want $ tied up in it, there are other options. Used revolvers (in .38/.357/.44) are a great value as long as you know what to look for.
Goood luck, let us know what you find.
