"How much is a Saab T/R worth with 100 hours?"
Well I would suggest it is worth a lot less than what they expect you to pay for it...and is therefore not money well spent.
You don't mention how much money is being asked, but if it helps you make a judgement then information on PPJN from Loganair, a UK 340 operator, suggests that they charge new FOs £8500 plus VAT for the type rating. How does that compare?
So keep your money and stay current if you can....why not spend a little of it on something fun like an aerobatic or tailwheel rating while you wait. Keeps the logbook moving forward as well.
If everyone would refuse to become involved in these scams they would quickly die. Unfortunately in these difficult times there is always someone, and often they end up regretting it.
