Allot of coin to dump on an old sled. Could upgrade to newer chassis and same power or more than the 740 for the same cost.
Add what sled is currently worth +/- 2g area and 2g for the big bore and your riding a rev 800 or 1000 just sayin
That being said though you can find them on eBay all the time and any Hp sled shop should still be able to hook you up
