I am purchasing these later on and wonder if there is any cheap sign ups or anything knocking about or any useful info in general?
Some sites will let you get Pokertracker for free but it will involve you signing up somewhere via their affiliate links so, in reality, they will make money off you in the long run. Personally, its just easier to pay the $55 directly. Pat and his team put a lot of effort into maintaining the product and its a steal at that price.
GT+ is free anyway. The other heads up display, Poker Ace HUD is the one you have to pay $25 for. Ultimately its worth having both as they vary in how well they work from site to site. Again, you can get PAHUD free via an affiliate link but its easier (and ultimately cheaper in terms of lost rakeback opportunity) to buy direct.
