Hi,
Yes I have advise for you, DONT buy on your first trip, look around and do your home work. When I bought, I made three trips and started off with one of the big boys and ended with a small local guy who knocked spots off the big boys for service and when it comes time to buy my next one, I will go back to him.
We all get carried away with the excitement of the purchase, the sunshine, the relaxed way of life, the idea of sitting around the pool having a nice cool drink of what you fancy, but it does rain, so stop and come back home and think about it, then maybe go again on your own to look around and ge to know the area, then go home and think again. Then you maybe ready to do the deed.
Enjoy it when it comes.
Dave
