Had this 856 given to me last week. It is my one and only full suspension bike, with no suspension. Anyone still making the coil conversions?
There are various options for shock replacement. I've seen people use budget elastomers for riding lawnmowers (or some such thing) or Risse probably makes some of the higher priced options.
Might need a rebuild kit for the fork and the rear. There is a US seller that may have those still. It's worth a rebuild IMO. The 95-97 Pro-Flex's are among my favorite FS rides. The Vector 2 fork is just amazing. Nothing tracks so confidently. The downside is they are a bit prone to collapse in sand/soft loamy soil if you over steer. The rear suspension is great for XC and climbing which I enjoy.
Had the bike been originally fitted with Risse (or similarly acceptable) shocks instead of the elastomers that went bad after 3-5 years I think there would be a lot more appreciation for this bike. It needs a shock upgrade to perform at it's peak for any length of time.
Nothing wrong with the budget elastomer route I've seen. A quite inventive solution to Girvin's yellow marshmallows going hard (or melting). Probably not as good as the much more pricey upgrades but I'm sure they do a solid enough job of smoothing out most bumps.
