I'd say your probably looking at $80.00 for the string and cable's but for the rest I'm not sure .I'd not put the tube peep on I'd go with a tubeless peep ,The tube I found would break at the worst time's and would have to be replaced ,and you wouldn't want it to break when your about to make the shot at a lifetime, it's happened to me on severel occasion's either the tube come undone or the tube broke. The tube attach's to your string or cable's and does affect your speed a tiny bit ,I'd try the Fletcher tru peep it will rotate on it's own without having to worry about whether your tube is going to come undone or break . The tru peep come's in 3 size's of hole's if your hunting only I'd recommend the large and if your shooting 3D I'd go with the small ,I use mine for 3D and hunting and have gone with the medium peep ,but I'll likely change to the large this season for hunting. This is just from my experience of what work's for me .
