Sending a MI424WR is not advisable. You should negotiate a G1100 from the official support. Nonetheless, you could get a second hand G1100 for under $40 on Ebay. Just making sure the unit is not a not-returned rental unit, or having the Frontier firmware.
Using TeamViewer opens doors to other issues. First, since built-in remote desktop server is a feature of the professional license, you might as well use that. TeamViewer can be installed on a Home license computer, then there is no point of paying extra for a Professional license unless you were looking for other features.
TeamViewer use a firewall-traversal technology similar to NAT slipstreaming, which carries a negative-connotation. NAT slipstreaming is technically a malware that can bypass firewalls to launch attacks to your other devices on the network. Unless you trust TeamViewer, or you believe their servers would never be compromised, then go ahead and use TeamViewer. Otherwise, you are routing traffic to a third-party, which may or may not be trustworthy.
