1. yes, check ebay sold listings for a general idea... but you're getting it at a decent price.
2. most of the ones out there are Korean... mine is Korean and perfectly happy.
3. the guitars can be repaired, and currently getting service would not be an issue.
4. i like the neck, its kind of like a epiphone les paul or prs se type feel
5. completely... you'll be impressed that it doesn't feel like anything less than.
1. It may depreciate a bit faster than a classic model/brand, but it's not bad.
2. There seems to be bit of variation in quality, or maybe I was unlucky with my first. The 5 upper frets on strings 1-3 were unusable due to buzz. I had to send it off for fret levelling (plek). The electronics are supposedly the same on both Korean and US-made models.
3. I'm a sceptic wrt repairs. Parts availability is questionable and may also vary a lot between locations. I've been told by my supplier that L6 is very restrictive wrt the distribution of parts and will only deliver parts to approved workshops. The electronics broke on my first JTV-59 within a few weeks. It took almost 4 months before I got a replacement. The distributors workshop was unable to fix it, which can only mean they had no access to parts. I got a new guitar under warranty, but that won't be possible once the warranty runs out. The replacement guitar was broken on arrival and I'm waiting to have it fixed or replaced again. I've been able to use the guitar for about 3 weeks in the 6 months I've owned it. I could have used it most of the time if I could have had access to parts to fix it myself as I do with the rest of my collection.
4. I like the neck. It is almost as chunky as my '89 LPC (50s neck-shape) and slightly wider which works well for finger-style.
5. It's a real guitar all-right. As a regular guitar, with magnetic pickups, it compares to other well-made Korean models such as the PRS SE-series. Then you've got the variax-electronics as a "bonus". The magnetic pickups are a bit hot if you are after classic LP-tones, but they can be swapped with whatever HBs you prefer.
At this point I'm on the fence wrt whether I'm going to keep the guitar or get my money back. The reason I got it was to be able to manage with just one guitar on a few occasions. It defeats the purpose if it is so unreliable that I always have to bring another acoustic and electric for backup.
