if u can get premade linkages for tha price i would say its worth it cause the time and hassle u may encounter with making your own might be discouraging...and thats the last thing u want...although i would still check out RAN429s post, like CatDog said...but i still think buying proper linkages would be best...Rotchesters should work very nice...cant wait to hear more about your progress on it though...
