Looking for Micromasters

[Tilarta]

I don't think it is possible, but I am trying to conplete my Micromaster collection.
These are the ones I am looking for:

Autobots	Decepticons
Air Patrol	Military Patrol
Sky High	Tracer
Eagle Eye	Bombshock
Blazemaster	Race Track Patrol
Treadbolt	Roller Force
Battle Patrol	Barricade
Big Shot	Ground Hog
Sidetrack	Motorhead
Sunrunner	Battle Squad
Flak	Meltdown & HalfTrack
Construction Patrol	DirectHit & Powerpunch
Neutro	Fireshot & Vanquish
Groundpounder	Constructor Squad
Crumble	Stonecruncher & Excavator
Takedown	Sledge &Hammer
Monster Truck Patrol	Grit & Knockout
Hydraulic
Slow Poke
Big Hauler
Heavy Tread
Hot Rod Patrol
Greaser
Hubs
Astro Squad
Phaser & Blastmaster
Moonrock & Missile Master
Metro Squad
Wheelblaze & Roadburner
Oiler & Slide
Powerrun & Strikedown
Overload	Roughstuff
Retro	TerrorTread
Surge	CementHead
Pipeline	Greasepit
Gusher	Airwave
Hothouse	Skyhopper
Ironworks	Skystalker
Groundshaker	Blackout
Countdown	Spaceshot
Full Barrel
Overflow

They can be either original G1 Micromasters or the Siege/Earthrise versions, as long as they are consistent in resembling the original toys (the two members of the Air Strike Patrol released were not, as they had Cybertronian jet forms).

I did look around, but 75USD for a 4 set or 100-115 USD for a Micromaster Base is a bit too expensive for me.

Also, if anyone knows of where I can find the Countdown Micromaster that came with Titan Omega Supreme for sale separately, I'd like to know where I can purchase this.
