Bleeding funnel

Hi folks,
As part of the " i want the most monwy i can get for my van as i'm selling it" plan, i thought i would replace the thermostat. I suspected back in January when i did a bleed, that it may have been sticky as i couldn't get the bottom rad hose up to a hot temperature no matter what i did or how many hours i did it (the bleed process that is). It got hot on a drive after so i left it at that and all has been ok.
But i bought a genuine Mazda thermostat at the time so i thought i couls fit it and therefore eliminate that and have it as a good selling point.
My question is this...what do people use for the funnel? I ended up using an oil filler funnel (a new one!) as i couldn't find anything at the time with the short notice that i had. As i have a bit more time, i thought i would do it with something that doesn't slip off and burn me!
So, what do you use and where havw you bought the components from? I've seen brass fittings used which would be the best option for fitment.
Cheers!

I use a plastic pop bottle with a peace of 10mm copper pipe fixed into the lid and the bottom cut off
I've silicone d and taped the pipe to lid
Then have an extra bit of pipe to lengthen and join to the breather pipe
And have a wire coat hanger taped to it so I can hang it on the passenger door gutter

Apologies if this appears twice, possible finger trouble here!
I nicked somebody else's idea of a jug with an inline tap. Got pipe, connectors and tap off eBay. Can dig back for specifics if wanted. Haven't need to clamp any of the joins.

what ever you use its a good idea to get something with the same volume as the expansion tank, it aids the see sawing if they are roughly equal.

I'd appreciate the details of the parts used if not to much grief

Hose:
Ebay item 261232997937 8mm clear hose £2.95
Unfortunately ebay won't give the order specifics and there are size variations! The only way I can get to the same price for the hose (BIG assumption here that pricing has remained the same) is 1m length of 3mm (thick) walls.
Tap size to fit:
ebay item ID 251424902421 £4.95
The straight connector was lying around in the garage so no details. Might have been a reducer. I think the bleed tube is 9-10mm ID but you don't want that to be too tight a fit. Sorry I can't be more specific and the kit is strapped under my passy seat. Using a plastic barbed connector into the bleed tube makes removal harder than if it were a smoother metal connector. The saving grace is that it is possible to turn the tap off after bleeding and let everything cool down a bit before separating the bleed tube.
Jug - From a discounted "broken" set of 3 in B&M !!
It's worth nipping the jug end of the hose off at an angle so it cannot suck itself to the bottom of the jug.

I bought a tap and tube this week, hoping to do the bleed at the weekend, if i can get the time. Heaters have warmed up again, so i think it's safe to say there is a pocket of air blowing around my system. Which is fine, i'll do the bleed, do the themostat and see where we are after that. Hopefully the bleeding will be a bit easier this time around.

When you do your bleed
Give it a few boys racer revs Vroom vroom vroom
It will shunt the pump
The pump goes faster the more revs you give
A great way of clearing stubborn air locks
Trust me I've been dealing with airlocks in my game for over 30 years
