This sort of carafe is very good for double sploshing. The ones on Amazon for £3.50 are not so attractive.

La Rochere, a french glass company
As Ba says, about 15, maybe more years ago, a large Californian wine producer gave you a plain one of these free, every time you bought the wine. In France the bulk Nicholas regional wines, for a short time, also came with a peel-off tin foil lid many moons ago. I have two of those.
For ornate cut glass decanters, the good ones are only cut glass on the outside surface, (so are reasonable to clean) the best value I know, are found in Help the Aged. They will ask you to make a decent offer. I have 3 acquired that way. Another beautiful cut glass fluted port decander I bought with wedding present money nearly 40 years ago, and another square cut beauty that my Mum bought me at the end of the 70's. A well fitting stopper is important for fortified, or claret over night
Of the ones you put up tribs, I'd probably go with the decanter that had the stainless steel funnel, that way one can filter out vintage port grouts with a coffee filter. However, how often will you be doing that ? I've filtered that way about every 4 - 5 years or so, and that is because I'm too cheap scate to tip the end of a good vintage port away. It's a long time since I found a claret with lots of grouts, and the small amount of light brown sediment in red burgundy is pretty firm these days. Old Penfolds 489. or 707 will throw some sediment.....if you can afford it !
For me, a couple of carafes are an essential piece of kit, a 0.75 and a 1ltr
