20 Liter SPD Mantle

In the market for a 20L mantle, whats everyones thoughts on the best for the price? Id get a techno heat from summit if it was in the budget. Ive been running a smaller Across international with no problems and their 20L sells for $1400, the gold leaf mantle seems better with the top heating, but is more expensive.
Anyone have a used 20L mantle theyd like to let go of?
