Sanity check needed: TR160 vs NLR GT Elite vs 6Sigma 6S-80 Did I let the price creep get too crazy?

I’m about to pull the trigger on a Trak Racer TR160 + NLR ERS4 seat, but I need to know if I’m buying something totally overkill. Basically I need someone to reassure me (or talk me out of this)

I went down the rabbit hole and the budget creep got real. Here is how my brain justified it:

• 6Sigma 6S-80 (w/ their seat): $895 CAD (Original plan)

• NLR GT Elite (w/ ERS4): $1366 CAD (Thought this was the "perfect" middle ground)

• TR120 (w/ ERS4): $1470 CAD (Only ~$100 more, so why not?)

• TR160 (w/ ERS4): $1495 CAD (Only ~$25 more than the 120... seems like a no-brainer?)

My Context:

I’m coming from old ikea table and horrible office chair with wheels. This will be my first 8020 rig because I have adult money now and I can treat myself lol.

• Current Gear: Logitech 11nm + 100kg pedals. • Future Goal: Upgrading to ~20nm DD. • Motion: No interest. • Main Goal: Zero flex.

Is the TR160 worth the extra cash over the 6Sigma just to be "future-proof," or will the 6S-80 handle a 20nm base just fine? what about the NLR Gt elite?
