Could anyone post some references to sources that detail the pros and cons of various procedures/agents for protecting and deprotecting amines, sans acetic anhydride or anything restricted such as that and preferably inexpensive/OTC.
Does anyone know what factors determine loss of product during/after protection?

US patent 3329690 looks interesting. It looks like you can make an imino ester from an ester and amine.
