The only Ibanez models that are equivalent to Vigier's builds are the J Custom's, and they are also a pain to get if you live in the USA.
There's only a handful of them that they build for sale in this market, most of them are made specifically for the Japanese market. The 2017 J Custom RG30 is pretty sick though, not my style with the unstained quilted maple though. Looks too much like a piece of furniture and not a guitar. But on the other hand, it has titanium neck reinforcements and stainless steel frets.
The Prestige line is okay, they are nice guitars and all, but they're not exactly comparable to a Vigier; the fret work on them is not too great, and most of them don't offer stainless steel frets like Vigier does.
The Premiums are very hit / miss, mostly miss. Not very good quality on those, the QC in Indonesia lets through a LOT of major flaws to the customer.
I'd suggest saving up and getting the Vigier, but that's just me.
The biggest PITA is going to be the neck, and depending how often you play, how hard you play, what kind of strings you use, etc, those nickel frets are going to wear out in no time.
I had to get my RG 7 Prestige level'd / crowned twice within 3 years of buying it brand new, each time I lost the guitar for a week or so and had to pay over 100 bucks to get the work done, then I eventually had it re-fretted with SS, again lost my guitar for a week and this time it cost close to 500.
So -- at the end of the day -- consider the cost (and inconvenience) of a re-fret or multiple levels / crowns by a competent luthier that knows what they are doing and factor that in, also factor in the chance of the neck bowing or the truss-rod breaking, which believe it or not, happens more often than you'd think, even on a JEM or any Prestige / MiJ Ibanez. I've even seen J Custom's with broken truss rods and twisted necks.
