Back to the OP:
'Standard gear' can be kind of limiting. In my experience, players like to shop for themselves or, if they don't want to have to deal with plowing through the Sears Roebuck Catalogue, they like a series of choices so they can get to playing quickly
So... limiting the gear to TL 12 my suggestion is this:
Everyone starts with:
<SNIP>
I handle it similarly in my own campaign, but even a bit more streamlined-
"Rather than waste time with equipment purchasing, we are assuming that the players are starting the game just after mustering out of their last service – and that because they live a life of travelling, they (like all who do without a starship of their own) travel light.
Various of the professions also have somewhat ubiquitous bits and bobs of “flavor” that accompany them, challenge coins for the military, field jackets for the scouts, etc. but that said, everyone can assume that they have a few changes of clothing, any equipment or possessions that were generated as part of the mustering out process of course, plus their Imperial Multipass, their Aide, and their Data Store – plus their life savings on account.
Assume that anything from now (or history) exists in the Imperium, either in an equivalent or an even more high-tech form. Rather than provide a confusing equipment list for people to buy from, if someone thinks that they should have some particular piece of gear before starting play just let me know and we’ll figure it out. You can assume that you are travelling with luggage the size of a footlocker or steamer trunk (aka a “jump trunk” – designed for interstellar travel). If you are wealthy then you have more space and can certainly have more gear. If you are dismally poor, you will have even less space for luggage to travel."
Most players (successfully) make a bid for some type of weapon and some type of armor, (service pistols are common result, as are combat fatigues with some AP), various characters often have augments due to their previous enlistment, and I embraced more recent sci-fi and everyone's Aide is a high-tech, almost AI (an "Expert Intelligence") that essentially becomes a henchman of sorts (or alternately a grog in the Ars Magica sense). I'm not super-interested in playing Traveller: The Shopping Trip, so this works pretty well for letting people have what they want and not get bogged down in the minutia of allocating every credit...
