200R4 swap questions

Was following this post and doing research on the same conversion in place of putting my 727 in my Duster.
So far the costs are pretty high...Wilcap was bought by Speed Gems and upped their prices it seems
$1,200 for the conversion kit (flywheel/adapter) (link)
$695 for the Quick 4 Stand alone (link)
$3,400 for a 700HP rated 200-4R Transmission (link) - could be other places to get a core and rebuild locally though so +/- $1500 i'd say
$??? for cables/linkages/converter/cooler lines

~$3,700 to $5,300+ in parts makes this definitely out of my budget for now. I do love that it doesn't require extensive cutting to get into an abody like other OD options. Will have to stick with my 727 for now but keep an eye out in junkyard dives for a solid core
