The main problem with the Lindner is the cost of the pages.
From what I can see, Safe is the main competitor.
They have quite a number of products.
This is the 'Artline' currency album (capacity only 30 pages):

They sell a range of pages:
1-pocket (250mm high) 1276
2-pocket (120mm high) 1277
3-pocket (80mm high) 1278
Priced at $1.60 each or $11 for 10.
The album is priced at $25 with 2 * 1-pocket, 4 * 2-pocket, and 3 * 2-pocket. Capacity is 30 pages. Code 1269. Optional slipcase 7373 is under $20, and you can buy the binder without the pages 1269SP.
The pages appear to come with optional inserts to allow you to put two notes into one slot.
You can also buy black interleaves, at about $0.50 each.
There is the 4-ring red album (capacity 40 pages):

Code 5100 ($25) + slipcase 5390 ($21)
or slipcase-style binder for $70
Or there is the 4-ring HIGH-CAPACITY (70 pages) compact album.
This is priced at $24 (code 480), plus $20 for the slipcase (489).
The available pages are:
2-pocket (145mm High) code 5490
3-pocket (95mm High) code 5491
$1.50/each or $13 for 10
10 interleaves for $5
Then there is the 11-ring compact album:
$25 for the album (708), and $20 for the slipcase ($20)
Pages with vinyl interleaves are:
561 1-pocket (245mm)
562 2-pocket (120mm

You can also buy various bundles:

Unpadded Morocco album + 7 * 3-pocket lightweight page + 3 * 2-pocket lightweight page $42 Code 7351
The Safe albums do seem to work out SLIGHTLY cheaper - the pages cost slightly less.
But the bigger advantages seem to be higher capacity (50 sheets vs 35), and the extra 5mm on the height of the pages. I have a good
number of 95mm banknotes.... Any thoughts on comparative quality and which brand people prefer?
I bought the Lindner, because when I was researching the albums, I didn't realise that the 'banknote albums' are just regular collectors
albums, and the Safe banknote range is cluttered with a large range of products, which I found it hard to understand.
But having gone through this, looks like a Safe 14-ring binder of some description would be the best album you can buy.
Are there other higher-end album choices?
