I own a Seasoft Ti 3000. You will have the TX and it is a great suit to learn and train with. However, if you decide to purchase a suit, I would recommend the Ti3000. The compressed neoprene and flexibility of this suit makes it more comfortable than the TX. The Ti3000 also uses SiTech valves.
Seasoft suits are very simple. No color, no designs, just a good, warm drysuit.
The valve placement is on the wrist of this suit. It makes it very easy to dump air. It is a little hard to get used to going from a shoulder dump, but not bad.
It does use neoprene seals so make sure you roll them under properly to get a good fit and seal.
The boots are the best part of the suit. They have a thick, sneaker-type sole so they are fantasic for shore diving. However, you need to make sure your fins will fit with the boots. Because the soles are thick, you may need to go up a size fin, if you use thin sole booties right now.
Enjoy diving dry,
