I've bought and sold a few Shoguns over the years. They're generally well constructed bikes. Good value items. Quality seems to be directly proportional to the model number. So a 1000 model will be a higher quality item than a 100 model. (I've got a Shogun 2000 in the garage right now waiting to be refurbished). They're good bikes & easy to repair. Brand new threaded parts are readily available for them. If it's a complete bike with good wheels and the frame isn't damaged it's probably worth around $50. Double that if you refurbish the bearings & polish it up.
