Hog Father, I am fairly new to the muzzleloader world so take what I say with a grain of salt. My wife was the one who wanted a ML so we did some research and she took the plunge,, twice.
When we started looking at all the different guns available, we decided to keep it simple and try to keep it as cheap as possible. The reason for staying cheap was to avoid sinking a lot of money into something that would only be a short term interest.
Simple to us was gun with a removable breech plug that didn't require special tools or gadgets.
To us, the break-open models fit this description. Easy to load, easy to shoot and easy to clean. What surprised me was how accurate these new style muzzleloaders are.
Now for the cheap. Take your time and do some research on the internet. Look at different ML's and write down the avg prices. That way you will KNOW if your are getting a bargain or getting hosed.
Look in the local classifieds, pawn shops and your local gun shops. Have your price list with you. I've seen used ML's selling for more then the new price, especially at the pawn shops. Don't be afraid to wheel and deal on a used gun. If dealing with a individual, ask to go shoot it. Also when dealing with a individual you MAY end up with accessories(powder, bullets, primers, etc) that will cost you extra at a store. Know the price of this stuff so you know what you are paying for.
Remember, cheap is not always a bargain and a bargain is not always cheap.
I don't know if your county now has the new muzzleloader season like our county does, but I have heard that Texas is proposing a primative arms season like Louisiana and several other states have. Something to consider if you would rather shove a bullet and pull the trigger. We'll stick with the ML's.
Whatever you decide on, have fun with it. Good luck and listen to these folks on here,,, they KNOW thier stuff,,,,,,,,,,, kinda...
