Yes, Indiana Berry has a very good selection of berry plants, I’m planning on making a sizeable order from them this year. One reason I like them is that you can just order one plant if you want, as opposed to a place like Nourse which require 5 minimum of black and rasps.
I got four blueberry plants from IB last year, and they have done well. I also ordered some rasps, but planted them too late (June) and one of five sprouted. The plants had good roots on them, I will say.
I did though, order strawberries (50 plants total) from Nourse last year. When I initially planted them we had a flash flood, so I had to pull them up and wait for the soil to dry out. Well, when I replanted them, they never sprouted. I contacted them and they said they’re prob dead, but would send me replacements free of charge. I got them and replanted those, and they did well. So, good customer service.
Anyways, Pense nurseries out of Arkansas have a good variety of rasps and blackberries to pick from. Their prices are very reasonable, about $3 per plant, but the shipping can be high ($20), but if your order is more than $45, shipping is free. I haven’t ordered anything from them, but @clarkinks got a big shipment of PrimeArk 45 blackberries from them recently. Maybe he could comment on them.

Regarding SWD, I don’t know that much about it, but I’ve heard they tend to come on more in late summer and fall, so floricane types, or summer bearers should be a better choice. Like Drew said, it depends where you’re at. Also, primocanes berries may not have time to ripen if you’re in a colder area, but you’re in Z7, so they should be OK.
