You can find the cheaper ones on sale for $350-375 depending on time of year, I cannot tell them apart, likely rebadged for whatever store they sell. Got mine last year for 350 at rural king, I think it was made in Italy?!?!, so far so good.... TSC runs them (I think tarter?) on sale once a year too, missed it and had to to to RK.
90% of the used ones I see for sale used have been stored outside catching rain for 5 years minimum, if you store it inside, even a cheap one will likely last you a lifetime.
But I'm tight like that.
