Need to buy 2 pairs of v-blocks - both large and small - any advice?

[ship69]

Hello

I need to buy:  A) a pair of small V-blocks and a pair of really large V-blocks. Do you have any buying advice?
(e.g. what brands, what features, where to buy from etc)

Background:

A. SMALL SCALE
I need the small v-block for working at small scale 
e.g. this sort of thing:  (e.g. 40mm x 32mm x 32mm). 

https://www.amazon.co.uk/Precision-Engineers-VEE-Blocks-CLAMP/dp/B08W4M44JH/

What about something more exotic like the Tormach V-block set?
They sit "below flush" at the sides which is quite clever as allows you to clamp the whole block in a vice, or use it on its side

Wait, here is a video!

 

 

 

 

B. LARGER SCALE
A friend has a pair of large "Seven inch" (180 x 115 x 45mm) v-blocks which he says he uses "every day" for all manner of random model-making task. (e.g. holding things down, holding things at 90° whilst glue sets etc:

i.e. This sort of thing:

Although that get pretty expensive (GBP200+)... also it's rather irritating to have the writing on the top.
Also would it be better to have a round or square cut trench down the middle?

 

Any thoughts?

Regarding the small (c. 32mm) V-blocks, I need them to be:

a) "pretty accurate" 
i.e. Accurate to say 1/1000 inch  (0.02mm)

b) made out of good quality hardened & heat-treated steel, so that they will resist being accidentally filed/dropped etc

Budget: £40? (but hopefully a lot less)

e.g. Brand: "White Hinge" (c. £35)

In general, are there any brands that you recommend for tools?
And are there any brands to avoid?

With thanks
