I own MX98 in 184 and 194.
For your need of cheaper one you have 2 options:
- Monster 98 in 184 (I also own them in 184 and 191). Can be found really cheap. IMO better than MX98 almost everywhere. Better in moguls, in crud, generally offpiste and especially in shitty snow. Require more physical input, but technically a bit easier than MX98. The only terrain where MX98 are more pleasant is well prepared groomers, easier to bend and to initiate turn.
- old stockli Stormrider DP Pro. Closest to MX98. With more performance, but more fragile. Can be found, sometimes. Can be found cheap, with a good amount of luck.
