There is a suitable Redline on ebay right now. Most of the bike is there and all it needs is a wheel set.
You can still buy Tuffs new from Skyway for around $160 shipped. Classic old school looks and almost bullet proof.
I'd say you could do a Redline for around $4-500.
Theres also the later Redlines like the 440 that are very similar to the earlier MXII's. They go or much less and are a good size for a rider.
I built mine for about $100 but I had a few bits already. This could be done for about $300.
Heres mine.
