Jumping in the conversation, I ended up driving to that seller and purchasing this machine. I am very happy with it so far. Was initially looking for a nice Consew 206. Purchased it and found PDF copies of the parts diagrams on Seiko website and a copy of the manual on Superior Sewing and Machine. It is virtually identical to the LSWN-8lb-2 and -3. The -3 has a different presser foot adjustment (not sure difference w/ -2 yet) Parts are completely available through various sources. Seiko was quick to respond via emails too.
Seller was great and very knowledgeable. I seriously ended up spending 3 hours there learning about this machine and others. Most of it after the sale. He had good technical knowledge and shared a lot. I would not hesitate to deal with him again. In fact, we actually struck a deal on another item I saw this week over text. Paul services sewing machines and refurbishes them.
My impression is the LSWN-8LB is it's a beefy flat bed machine. It looks built well and very similar to a Consew 255? Huge top loading U bobbins. I've stitched 2 to multiple layers of veg-tan, some belts, ect this week and it just goes. So far, my impression of Seiko is pretty good. If it stays this consistent, I'd buy another Seiko (new or used).
Thanks for letting me interject.
