I like Pemican brand, Tillimook, or if you have a QT near you try the store brand, it's actually pretty good, like $10 for a bigger bag seems like it's called Trapper or something like that, it's been awhile since I bought.
Beef jerky outlet has some good stuff but I prefer to buy in the store from them as a couple times I've had it shipped it was stuff that was getting close on their use by date.
If you consistently eat jerky it's not hard to make your own, you can pick up a decent large dehydrator for $120 or so off amazon and there are recipes everywhere for marinades or rubs. It's a lot cheaper than buying and a lot healthier than what you're getting in a package. Plus you can dry fruits/veggies, spices, make fruit roll up, dry roast nuts, etc with it depending on what you buy. I've got a couple I've bought over the years but this is the one that sits on the kitchen counter most all the time, Between drying apples, pears, orange slices, lemon slices, jerky, etc it usually gets used 3 or so times a week, I bought when it was on sale on black Friday. It's still got a $40 coupon on it to bring it down to $150

Depending on where you get your meat you'll get anywhere from 1/2 to 1/3 weight of finished jerky to raw meat. If it's a good dry cut you're starting with then it's more like 1/2, if it's commercial packaged it's more than likely injected with water to increase the weight and you'll only get about 1/3 the weight when it's dry.
Maybe buy some different flavorings and type of jerky (beef, chicken, pork, fish, etc) to find what you like and then try making a batch up yourself. If you have a toaster oven you can do small batches easy enough just to see if it's something you like doing.
