I was leaning heavily towards a caldera until I wet tested a Bullfrog R7L and fell in love, So I bought it. It's a floor model leftover 2014. Anyway bullfrog sells the DuraStep. Which I can find online for under $70. It says it's rated for 700lbs however it doesn't inspire any confidence when using it. So is it really sturdy ? Any other recommendations for steps besides making my own? I have zero carpentry ability and zero painting ability. Concrete pad construction is slated for the 30th so after its finished and concrete cured I'll get it delivered and set up. Last question is I was going to use the spa frog but my dealer highly suggested trying Baqua so much so that they are giving me a 3 month supply free. Anything I should know about using it other than the lesson I got today- add chem once a week on average, test strips will dictate. Doesn't evaporate like chlorine and bromine and only goes away with use.
