Ugh I just paid $950 on prime day for this bad boy. Worth it if you already have the base.

If you have the AC200PL, make sure you have the P090A expansion cable already, since they have been sold out for two months and might not bring them back since they're discontinuing the AC200PL/AC200L soon in favor of the non-expandable Elite Series.
