I had two Grisleys but got rid of the Orion 20 keeping just the Nimbus Paragon. The Orion came with awful Acera-X components which all broke within a year of hard use: one of the cranks snapped! I replaced all the bits over time with Deore LX/XT but it eventually ended up at the recycling centre two years ago.
The Nimbus came with Deore XT everything apart from the mechs which were XTR, Mavic 217 ceramic rims, Fox Alps 4R rear shock, Judy fork, magnesium handlebars, XT SPDs and titanium seat post. Quite a bargain in 1997 at £1299.
