I don't have experience w the reactions, but idid get gara hf 2000's and they are fine in shallow water...they are stiffer than the 3000's so perhaps the 3000s are a better starter.
there is a tension in this sport that you will soon come to know which is the cost of gear vs the need for it. as an example, when i started diving I was using a US Divers set for 40 $ that I bought at sports authority and a fiberglass polespear, I could get fish, but I felt the limitations of my gear very quickly. I upgraded my fins and mask together to a Riffe sight mask and cressi gara 2000's. at that time I had a lot of friend telling me to wait and just get a really nice mask and carbon fins. I decided that was too pricey and I bought them.I love the fins and the mask but quickly found that the mask, while 100x better than my previous mask, stilll had too much volume for my comfort and was bulky on my face so I kept the fins and got another mask, the technisub micromask..I also went on to buy the awesome pursuit carbon 90cms.
the point is that there is acceptable gear, good gear, and garbage gear.
you can buy a lot of acceptable gear or just a few pieces of good gear (this take trial and error).
for you, i would say, get something inexpensive to see if you like this sport and want to make it part of your life, and if you do, then upgrade to the best gear you can cos it will save you money over the long haul.
