2 amp transformer alternatives
SE isn't for "shop for me" questions, but it sounds like you just need one of the basic tools-of-the-trade: awareness that a supply network exists.  For general electronics, try Mouser, Digi-Key, Arrow, Jameco, Newark, Galco, and often you get lucky on Amazon (Prime, yay) or eBay.  

For this particularly, you have one more option.  24V transformers are widely used for control voltage in heating and cooling applications, which opens up a wide variety of products from another tranche of suppliers.  For instance your local heating/cooling supply, some code-electrical distributors, Lowes/Menards/HomeDepot, Grainger, and numerous products on Amazon.  

This is why I often recommend people homebrew stuff out of 24v transformers and 24v-coil relays, because they are readily available dirt cheap out of the heating-cooling parts bin.   Need a 30A relay capable of interrupting a big inductive load?  A/C relays.
