I have speedo endurance swimming trunks and I can totally recommend them. Only thing I would say is that they are *very* hard wearing - I've had mine for 10 years now, and they still look fine on the outside (the white inside is slightly grey though), so I can't justify replacing them, so make sure you buy a style you'd be happy wearing in 10 years. Mine are proper speedo small trunks, which I'm cool with still, but most people would rather wear jammers nowadays (and jammers are supposed to be very slightly faster too).
Goggles are different for everyone, nothing to do with price or quality of brand, all to do with whether they fit your head.
They also wear out over time if you swim a lot and start to leak. Especially I think if you swim somewhere with sand or gritty mud when you're getting out. A pain if you buy expensive ones (which don't appear to last any longer). Most pros use an almost new pair of goggles for any important race. I tend to lose them quicker than I wear them out, I'm a right bugger for losing goggles. I also had a pair eaten by a toddler pretending to be a dog, teeth through the seal = instant ruined goggles. Oh, and the anti fog wears off roughly straight away, so everyone ends up spitting on their goggles before they start a swim, that only really matters outdoors though.
I usually spend between a fiver and a tenner on goggles, because I like a soft fit.
My current pair are arenas, they've lasted all summer, and I've been swimming an awful lot almost exclusively in rivers or lakes, so I'd rate them.
I also had TYR goggles - I wouldn't rate them, they have a stupid thin strap, and if the strap breaks they won't fit a normal replacement, so it's new goggles time, and otherwise they weren't that good either, got foggy uppy very quickly. I think I had Zoggs and Speedo before that, they were fine too.
There is also a trend amongst a lot of very good swimmers, particularly pool swimmers, for the swedish style goggle - these are dirt cheap, unpadded, and come as a kit where you tie the nose bridge together just right for you. Some people also file down the edges of the eye cups to make them smooth. Worth a try as they cost next to nothing - eg.these.
