To make it easy to get started on the forum each user gets a small storage allowance to allow them to attach log files, tune files and pictures to their post. When you have used up that allowance and try to attach a file you will get an error message stating your file is too large to upload. The way forward is to upload the file to an online drive service and use a share link to the file. Google Drive and Onedrive are probably the most common free options in western countries so I have done a quick guide on those two here.
There are many other options such as Dropbox, iCloud, WeTransfer, etc that usually follow a similar process.

Regardless of what you buy getting the signal into the ECU via CAN is far better than via an analog signal so aim to buy something that is CAN capable. The Link CAN is very configurable and so can be setup to work with almost any CAN based Lambda device.
I have seen cheaper Lambda devices be a bit laggy and any analog based signal is prone to ground offset issues and lack of resolution.
