I had an Archer 2 and now share a TB 20. The TB 20 is between Arrow and Saratoga in terms of performance and comfort. It is well put together and performs very well. Spares have been no problem, RGV at Gloucester can get most things overnight.
The Rnav and IFR capability are dependent on the avionics fit but most TB20s are capable and have three axis autopilot.
Google Peter2000 for a very detailed owner website there's also a great Socata TB forum in the USA.
