I was in the same boat very recently. I did a lot of research online; browsed fora, read reviews etc. I live in a smallish city with only one real music store and it is not a big box chain, so what they have in stock is what you get and if you want to try a guitar and they don't have it, well, they'll order it for you which means I get to try it in store and buy it, unless it has some defect. That coupled with the pandemic and not being able to get in store anyway for a long time, i had to shop online.
I agonize over even small decisions, especially when I can't just go see if I like it. But, before I narrowed down the bass I wanted, I had pretty much narrowed down the retailer from whom I wanted to make a purchase. And after asking on here I was reassured it was the right choice. I chose Sweetwater. They have a really good return policy. They add a personal touch by hooking you up with a salesperson that is a musician themselves. I got Jack. He's a really nice guy. Plays upright and electric as well as some other strings. He talked to me for 44 minutes. Never once did he seem like he was in a hurry to finish the sale and get rid of me. I asked about the weight of the bass and the ones they had in stock had not yet been weighted and photographed. We talked about my bad shoulder and back and he assured me he'd put a note in to send the lightest one they had available. Jack also threw in a free strap (3.5 inch Levy leather, not some cheapo nylon) one of their house brand 20 foot cables (Lifetime warranty which Jack said, "If it goes out, call me and I'll ship you a new one as it's cheaper to replace than return ship and repair") and a bag of picks all on the house.
Sweetwater wants your business and they want to keep it. Everyone I talked to said their 55 point inspection is legit, though like anything I am certain some things slip by. It's not a setup, but it should be in spec and a setup should require just a little work on my part, hopefully. I say hopefully because I ordered Thursday. It should be here Wednesday according to FedEx. I had more interaction with Jack than I did with David from my local music store when I ordered a brand new American Standard Jazz bass in the mid-'90s. When I get the bass, I will definitely have a New Bass Day thread and I can give you a more thorough opinion on the inspection and condition aspect at that time.
Check out Sweetwater and see if it sounds like a good fit for you. If I had a guitar center less than three hours away, I might have gone for that because I know folks can return online orders in their store and that you can call them for less than MAP offers. That said, I was really impressed with the customer experience at Sweetwater. If the bass is good, they will definitely get my business when I buy a new amp after Christmas. Standard disclaimer here: I do not work for Sweetwater in any capacity. I just tried them out over some other online retailers for the reasons mentioned above and haven't even received my first order from them yet! Whatever you decide, welcome back to the bass world, enjoy your time on Talk Bass, and have fun!
