28CDN/26.22US isn't really that bad for 20# as it's $7CDN/$6.55US per 5#. Granted most places charge an initial refill fee then increment by a smaller amount for the next sizes up.
I guess the prices under $100 for a 10# aluminum cylinder aren't that bad. Divide that by 5 for $20/year and just trade it before the hydrostatic date expires.
