The RC4WD 4200XL excavator is a great machine for a budget price. Yes it's around 3K, but compared to the German machines that are 10K or more, it's budget friendly.
The wheeled loader from Aliexpress.com & sold by seller Emo, &/or Faroe is an excellent wheeled loader. This/these seller(s) also offer an EXCELLENT Volvo articulated haul truckWhen I bought mine last year it was $2660.89 & that included shipping. I did have to spend about $100.oo to upgrade to a MagoomHRC hydraulic valve. I upgraded as mine was leaking the instant we turned the pump on.
BOTH machines are fully hydraulic. BOTH machines will need EVERY nut/bolt undone, & add loktite to them. Both machines if you DON'T do this, will have bolts that back out & break off. There are several videos of RC4WD excavators (Most have had extensive custom body work done to them, but are still RC4WD machines) & of the Faroe loader on my YouTube channel.

The STAY AWAY FROM hydraulic RC stuff
Emo &/or Faore tracked loaders, excavators, mine haul truck, bobcat/skidsteer.
These machines are a great platform to upgrade, but are problem plagued right out of the box. Track pads are crappy & break quickly. These products ALL use the same failing problem plagued 90 degree gear drive motors to propel them.
Hopefully this helps
