I've never owned a Magma but then I can't say my solution was very economical.
My only hesitation with Magma was that they advertise "marine grade" steel. It's difficult to find anything specific from Magma on exactly what steel they use, but several resellors do mention "Made of 100-percent 18-9 mirror-polished stainless steel" (http://communications.mystuffdeals.com/magma-grill). A little research on wikipedia shows this is better than standard steel, but categorized as SAE Grade 304 (https://en.wikipedia.org/wiki/Steel_grades).
Most vendors claiming marine grade steel for any product specify SAE Grade 316. Here's a page of grills of which about half are 316, for the most part the items that don't say 316 don't say "marine grade" (http://www.gumtree.com.au/s-marine+bbq+stainless+steel/k0). The difference is molybdenum which resists salt.
So how long have these grills lasted for you? I see one person said 20 years, but was that really hanging on the rail the whole time? Unfortunately I see another post that says the old Magmas were not the good ones. Talking to my next door neighbor his first Magma lasted one season uncovered, then it was completely rusted inside and out. His second and current magma has lasted several years so far, however he has replaced the internals once. Clearly a decent cover is worth the investment.
I ended up getting a Galleymate (http://marinebarbecues.com.au/marine-barbecues/galleymate-2000/) which has worked really well. I figure Australians know sailing and bar-b-queuing. I went with the rail mounts, they have a variation of what is shown on that page that works with a curved rail. Then I added the diagonal telescoping rod. Claims to work in winds up to 40 Kts, which I can't say I've tested yet. I can say that the very low settings work well in the calm, but with 15-20 Kts of wind the flames will snuff out at low settings. It's 2 years old and after a decent cleaning it looks almost like new.
