I've been in your shoes, so I had to go through much of the same thought processes for what to buy. If you can go up to around $300, you get access to many more choices--but that wasn't an option for me either.
I considered the Tok. It has a lot of historical appeal to me. I liked how inexpensive the 7.62x25 rounds were. However, if you shoot at an indoor range, note that many of the milsurp rounds have steel cores, and many ranges do not allow them.
Folks have mentioned the milsurp CZ82. I think this is your best bet. You are not getting a budget pistol, but rather a taste of high quality at a low price. You may see why so many folks are so high on CZ.
Pros:
- The '82 has one of the best triggers you will find outside of single action 1911 territory.
- It is heavy, but still concealable if necessary.
- It is built like a tank and easy to field strip (but difficult to detail strip so don't do it unless necessary!).
- It is extremely accurate.
- Comfortable to shoot.
- Ammo is cheap.
- It is double action/single action, but can be carried cocked and locked with the safety on, just like the 1911.
- It has a polygonal barrel (i.e., no visible rifling, but rather an almost imperceptible angle in the barrel to give the bullet spin). This means that barrel wear is generally not an issue, and you get a smidgen higher velocity.
- The pistols are easily found on the web within your price range (SOG, AIM, J&G, etc.).
Cons:
- Their finish is often beat up, but they are easy (and cheap) to refinish. I have actually had quite a bit of fun with mine as a project gun.
- The 9x19 round is not the best possible choice. But it will do the job for self defense. And it will certainly punch holes in paper targets.
- 9x19 is pretty easy to find on the web, but generally tough to find locally. This means that you need to plan ahead when you want to shoot, and it generally means you need to plan to buy in bulk (in contrast to stopping in at Walmart to snag 50 rounds if you need them).
Some of the other pistol choices will leave you itching to upgrade, and maybe even bitter reminders that you couldn't get into something of higher quality. But you may find yourself wanting to hang on to the '82 on its own merits even when your budget grows. My budget has grown, and I have bought several other pistols, yet the '82 will remain as part of my collection.
Good luck!
