Keep in mind the 1.8T is the most likely (of 4cyl engines in Mk2s) to have oil consumption issues due to the piston design. It's an EA888 which is based on the early Gen 2 design only without the VL system and destroked to 84.1mm. Meanwhile the Gen 1 EA888s never had this issue (different pistons); and, as alleged by Audi, the actual Gen 2 engines in the Mk2 TTs were all new enough to have revised pistons (only earlier Gen 2s in the longitudinal cars were affected).
TBH I would just get an S model if buying an Mk2 if looking for "a bit if grunt". It's the best bang for the buck, pretty quick even completely stock, has bigger brakes (shared with the 3.2L), and is relatively cheap (it doesn't have the price premium like an RS does). Main thing to be wary about is the suspension but as long as in good condition you should be ok.
Otherwise if "scared of magride", buy a 2.0T with the Gen 2/VL engine in it. But IMO the EA888 has more potential for severe-problem-causing issues if left unchecked.
