Industry Values for Beta (β) in BJT current amplification
As a general answer to what values of B are common out of all the BJTs commonly available right now;  One quick way to find out what's common would be to search for what's in stock at the major distributors, (Mouser, Digikey, Avnet, Arrow, etc).

A search on Digikey for all currently stocked BJTs in active production gives 3723 unique manufacturer part numbers.  Given B for each of those part numbers we have the following statistics.

Minimum B = 3 (lowest value)
Maximum B = 1000 (highest value)
Average B = 559 (arithmetic mean)
Median B = 100 (center of the list)
Mode B = 100 (most common value)
90% of the B values fall within the range 25 to 750.
80% of the B value fall within the range 40 to 270.

I used the values of B in the Digikey database to generate the above statistics.  The values of B in the Digikey database usually match the typical value given in the table in the manufacturer datasheet for each transistor.  The value of B is usually given for a specific operating point that the manufacturer thought was relevant.  

Generally B is different for each unit manufactured and can also change if the operating conditions change(temperature, collector current, collector emitter voltage, etc).  So my answer should only be taken as a rough estimate of what's out there.
