I 'helped Santa' find an 'economy option'...
...& ended up with Mirror Models #35853
It was NEARLY 1/2 the cost of the MiniArt one WITH the blade.
Just looked out on eBay, till 'the price was right'...
...no sense in paying full price, NO WAY.
I personaly like the non-blade tractors better anyhow.

BEWARE OF THE MINIART DOZER KITS !!
Their track-sections are in FOUR PARTS...
...Mirror Models & Trumpeter (ChTZ S-65) track-sections are in THREE PARTS.
The MiniArt kits have the 'bearing-pin' as a SEPERATE PART !
Mirror Models & Trumpeter have the bearing-pin as part of one of the 2 side-pieces that mount on the tread.
The bearing-pin is EXTREMELY SMALL !
I haven't tried assembling MiniArt tracks...
...but thought I should point this out.
It's probably a FREAKIN' NIGHTMARE !
(like most MiniArt kits !)
I'm part way through my D7.
It's very nice, ZERO flash, sensible runner locations etc.
Lot of parts though.
