Most affordable class to start out racing? and cost of everything?

"Cheap" racing can still be pretty expensive, but it is at least much less costly than some other forms. Spec Miata is the most likely to come up here, as well as things like Formula Vee of Formula Ford having the potential to be economical (SRF can be as well).

Key factors to look at would start with the overall cost of the car, followed by tire specs and how long you can expect those tires to remain competitive, and then part availability. Even if you find a great car for $3k, and can fully prep it and get it ready to run for another $5k - you'll quickly wish for something else if you cannot readily find replacement windshields at a junkyard or have to buy even the occasional new body panel from a dealer! And if you are running big radial tires that are uncompetitive after each running, the cost of the car winds up being a drop in the bucket. The above cars all are among the least costly options to start in, and used parts are readily available in most cases, and while tire budgets are always going to be a major expense, the particulars here are much kinder.

Car prices will be more attractive when buying something someone else has already sunk the time and effort into getting together, but there is a major caveat to that which basically starts "why are they selling." There is a reason why one Spec Miata will be $15k and another $5k... the cheaper may be good for a novice planning to learn though, but it would be reasonable to still expect that you may have some issues that will require some investment in the near term.

Lastly, while attractive on price, don't go short on safety equipment! A good helmet and suit and HANS, etc will be a big part of your initial budget, but the last thing you ever want to think is "I wish I had better safety equipment." If you ever need it, it will be worth whatever you had to pay! As such, make sure you budget generously for this at the start (as well as for a good cage, seat, etc, if you are doing the build out yourself... or make sure you have these on any car you buy).

late model engines alone can cost up to 60k....so i dont know what you can afford, but id say try the street stocks and see even if your good. it would be a huge waste if you got a late model and be very mad and lose thousands of dollars every week

You can save some cash by buying used cars and equipment. Here's a site that can help.
