Thanks guys for your replies... I did go ahead and buy the 545, it was from an auto upholsterer who was moving back to his home town He gave me some demonstrations on it and show me what it is capable of doing. I have had it now for a week or so and I have been practicing on it, and I am happy with my results so far. I purchased Don Taylors book and it has different practice lessons I have been doing.
I am in Sarasota so I may call on you sometime, thanks for the offer.
