Hi Tony,
Welcome to the fold. glad to hear your enjoying it. Nothing wrong with secondhand Kit there are some real bargaines out there. All mine was bought off Ebay motor, wing, reserve, GPS, Vario, radio, gloves, helmet, flying suit, windsock and wind meter it can be a bit of a gamble but do your research you should be ok. If you can talk to the seller before you buy it helps a lot. If they dont seem to know about what they are selling I would be a bit suspect especialy in the wing/motor department. Apart from that its usually ok at least in my experiance. I think i spent about £2500 in total 1/3-1/4 new kit prices.
Hoping to go to the flyin myself and I belive a few of the other guys are going as well so hope to see you there. Cheers for now Col....
