To break the choices down financially (a 12ga or 20ga are same price / then the 28ga or .410 are a little more ) :
Grabber $ 400 ( manually index ) / 28ga or .410 are $425
9000 GN $490 ( adds auto indexing ) / 28ga or .410 are $540
Auto Mate $ 1,040 ...( electric / auto indexing )
9000 HN $ 1,030 ...( hydraulic - with pump and motor )
Once you have the automate base - you add another loader for $ 500 each for 20ga / or $540 for the 28ga and .410 ....
Once you have the hydraulic pump and motor - you add another loader for
$ 550 each in 20ga ...or $600 for 28ga and .410.....
Prices are current - that I pulled from ReCob's Target Shop online / good folks, easy to deal with ...but lots of places carry Mec loaders..
------------------
So
auto indexing is a $ 90 issue...in a 12ga or 20g loader....
The Auto Mate is more portable than the Hydraulic ...but in my view, the hydraulic is a better option / but only marginal issues between the two systems.
----------------
Spolar Gold press ( 1 gague ) is $ 1,650
Add Hydraulics option is $ 1,295
To add - tool heads for another gague $ 325 each....
So one gage, hydraulic is $ 2,945
-----------------
If you wanted to reload all 4 competition gagues ( 12, 20, 28 and .410 )....
Spolar Gold Hydraulic would be $ 3,920
Mec 9000 HN hydraulic would be $ 2,780
Mec Automate ( electric ) would be $ 2,620
Mec 9000 GN ( auto index / manually operated ) $ 2,060
Mec Grabber ( manually index / manually operated) $ 1,650
-----------------------------
Not that everything should come down to cost.../ but we know it does with dreaming.../ sorry my friend...
