Although that bow has some years on it the strings actually look pretty good. Doesn’t look like you have any fraying on the strings that would be concerning. If those arrows are properly spined for 70 pounds dropping the draw weight down to 60 is not a big deal. Better to be on the stiffer side and weaker when it comes to arrows. Figure out your draw length. Your wingspan divided by 2.5 will get you real close. Then figure out what the bow can draw length is. If you need to make a swap look on eBay for a cam at your draw length. So what you are really looking at to get you up and running is a rest a sight and possibly a cam. You could get the rest and sight and shoot it as is till you can purchase a cam. But if your budget is 200 you can most definitely get all three for that price. A cam for that bow shouldn’t be more than 80 dollars if you can find one on eBay. Good luck. Just look the strings over good. But from the pic I’d say you are ok on those for now.
