In a TT, the main bearing and drive system is the key issue, not the suspension. I have a high end TT that has no suspension at all. A suspension is simply a type of vibration isolation.
I think that the MDF construction of many newer entry level TTs is a cost cutting measure.
Older Rega Planar 2 TTs came with glass platters, but not with the RB300 arm. They came with RB200, or RB250 arms. The RB250 is a better one than the RB200. The Rega Planar 3 came with the RB300 arm.
Suspensions vs non-suspensions is a thing that audiophiles have argued about for years. Both types have their good points and bad points. I would say that it is a personal choice. Generally, lower cost suspension TTs are less prone to vibration, but are more complex in construction, and may require adjustments. Non suspension TTs may have more vibration issues, but are less complex, and need no adjustments of that type.
I generally believe that in a cost-oriented TT, the less parts the better, because every part costs money. If they have to make alot of parts and complicate the assembly labor process, the TT will either cost more, or they will have to cut cost in the important areas of bearing, motor, and platter, and possibly tonearm. That is, if they are going to keep the same entry level price point. You can see that many makers are going to MDF already, to cut costs. If they had to include more parts and labor costs for a suspension, then the price would surely rise, or the quality of the important parts would surely fall. No free ride.
